Abstract: PURPOSE: To provide multilayer film of iron/iron nitride having low satd. coer cive force and magnetostriction by plating an iron layer and a nonmagnetic spacer layer of iron nitride on a substrate successively by a sputtering method to specific thicknesses respectively under specific conditions.  
     CONSTITUTION: The surface of the substrate impressed with a bias of about -25 to -125V under a total pressure of about 3 to 10mTorr and input electric power of about 100 to 400 under an inert gaseous atmosphere by the sputtering method. This iron layer is preferably formed to the layer contg. about <2% N and having about 100 to 2000Å thickness. The nonmagnetic spacer layer consisting of the iron nitride layer is then formed on the iron layer by sputtering at a bias of about -25 to -100V under a nitrogen partial pressure of about 1mTorr, total pressure of about 5mTorr and input electric power of about 100 to 400W under the inert gas and nitrogen atmosphere to about 20 to 1000Å thickness. The iron nitride layer preferably consists substantially of Fe 3 N or Fe 4 N, contains about >20% N and is formed to a thickness of about 2 to 5 times the thickness of the iron layer. As a result, the multilayer films of the iron/iron nitride having the low satd. coercive force and the substantially zero magnetostriction are obtd.

Filed: 1990-11-30
Abstract: PURPOSE:To prevent a terminal side from being influenced by the concentration of load into a host machine or the generation of a fault by providing each of plural terminals with a control means for controlling a log-in service execution means and a display means and selecting one of plural log-in service offered from plural host machines. CONSTITUTION:Each terminal has the control device 19 and the display device 18. The log-in service execution device 16 executes log-in service in accordance with set data stored in a storage device 14 and requests the display of the log-in service to the control device 19 of the terminal. The control device 19 displays the log-in service on the display device 18 in accordance with the display requests from four host machines. The control device 19 selects any one of the host machines and controls the log-in service execution device 16 to select the host machine for executing log-in. Since the host machine for offering log-in service can be selected from the terminal side, the terminal side can be prevented from being influenced by the concentration of load to the host machines or the generation of a fault.
